Fatigue Study of a GRP (Glass-Reinforced Plastic) Pedestrian Bridge
Static and cyclic load tests were conducted on a 16-ft long bridge constructed with fiberglass materials. Approximately 1.6 million cycles of loads were applied to the deck to study the fatigue characteristics of the bridge. The location and magnitude of the loads were selected to accelerate failure of elements and joints in the structure. Upon completion of the cyclic load program, an ultimate static load of 16,640 lb was reached before the bridge failed. Experimental strains, deflections, and acoustic emissions were monitored during the load tests. Test results indicated that cracks in the bonded joints formed and extended under cyclic loading. A theoretical analysis of the behavior of the bridge was conducted by means of a finite element model.
